Calla Lily Plant Named &#39;A405&#39;

ABSTRACT

‘A405’ is a new variety of calla lily plant having white colored spathes that produces 6-10 flowers per rhizome. The flower stems are about 30-40 cm in height. The leaves are green with numerous whitish spots and have a leathery texture.

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional PatentApplication Ser. No. 62/766,213, having a filing date of Oct. 5, 2018,and entitled “Varieties of Z. aethiopica Calla Lily Plants”, the entiredisclosure of which is incorporated herein by reference.

Botanical classification: Zantedeschia aethiopica.

Varietal denomination: ‘A405’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of callalily, botanically known as Zantedeschia aethiopica and hereinafterreferred to by the cultivar name ‘A405’.

‘A405’ is a product of a planned breeding program, which had theobjective of creating Zantedeschia hybrids for pot flower production ina wide range of colors with a large, classic flower shape. The breedingprogram began in 2007, and the new cultivar is a seedling selected fromthe crossing of Zantedeschia sprengeri seedling A080017-211 (femaleparent, unpatented) with Zantedeschia sprengeri seedling A090001-3 (maleparent, unpatented). ‘A405’ was selected in 2014 by the inventor in ‘tZand, The Netherlands as one flowering plant within the progeny of thestated cross.

The first act of asexual reproduction of ‘A405’ by tissue culture wasperformed by the inventor in September of 2014 in ‘t Zand, TheNetherlands. Subsequent asexual reproductions by tissue culture at thesame location have demonstrated that the combination of characteristicsas herein disclosed for the new cultivar are retained and reproducedtrue to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plantsgrown from 12 to 14 weeks in 14 cm pots in ‘t Zand, The Netherlandsunder greenhouse conditions, which approximate those generally used inhorticultural practice. Color references are made to The 2001 R.H.S.Colour Chart of The Royal Horticultural Society of London, 4^(th)Edition, except where general color terms of ordinary significance areused.

The present invention has not been evaluated under all possibleenvironmental conditions. The phenotype may vary with variations inenvironment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to bebasic characteristics of ‘A405’ which, in combination, distinguish thiscalla lily as a new and distinct cultivar:

1. Compact plant habit;

2. Numerous leaf maculations; and

3. High inflorescence production.

Table 1 provides a comparison of ‘A405’ to its parents, as well asZantedeschia aethiopica variety ‘Colombe de la Paix’ (unpatented).
